"What happened to research days?"

#PokemonGO: After Feebas and Clamperl research days, I think most people expected it to be a more common occurence but I dont think theres been one since. Was there any news from Niantic about the future of research days?Side question: what so people think about research that is extremely hard but guarantees a shiny or has a high rate? via /r/TheSilphRoad https://ift.tt/31TJSEY
